1. Homework Statement [/b] assume g = 9.81 m/s2, and friction can be ignored. A gun is fired horizontally at a target lying on the ground 188 m away, and the bullet hits the center of the target. The muzzle velocity of the gun (the speed with which it fires bullets) is 387 m/s. a) How...

Hi I need help solving this problem. Thank you. 1. Homework Statement [/b] Given: assume g = 9.81 m/s2, and friction can be ignored. A ball is thrown into the air at speed 43 m/s, at an angle of 53.7 o to the ground. The ball lands at the same elevation as it was thrown. a) Find...

Hi, I missed the first lecture of my physics class and need help answering these simple questions. They have to do with adding and subtraction and multiplying unit vectiors. What do they mean by direction, this is in degrees? Also, I am not sure if this is possible but a diagram would...
